A Bucks County jury has found a man guilty of setting his Richland Township townhouse on fire during a drunken argument with his wife. Jurors convicted 37-year-old Brian Bonekemper of arson and other offenses, including public drunkenness. He set his wife’s clothing on fire in March, heavily damaging his townhouse in the Walnut Bank Farms development and causing some damage to an adjacent unit. His lawyer argued that he was too drunk to know what he was doing.
